Acceptance and commitment therapy combined with vestibular rehabilitation for persistent postural-perceptual dizziness: A pilot study.

PURPOSE: This study investigated the feasibility of acceptance and commitment therapy for persistent postural-perceptual dizziness and preliminarily verified the long-term effectiveness of the therapy. MATERIALS AND METHODS: This study implemented the within-group pre-post comparison design. We enrolled 27 adult patients who met the criteria of persistent postural-perceptual dizziness. They underwent a treatment program including acceptance and commitment therapy combined with vestibular rehabilitation once a week for a total of six sessions. The primary outcome was changes in the Dizziness Handicap Inventory score 6 months posttreatment. RESULTS: All 27 patients completed the acceptance and commitment therapy + vestibular rehabilitation program, and 25 patients (92.6%) could be followed for 6 months posttreatment. For 27 participants, the scores from pretreatment to 6 months posttreatment significantly declined (P < .001), and the Dizziness Handicap Inventory effect size was 1.11 (95% confidence interval = 0.80-1.42). At 6 months posttreatment, 11 patients (40.7%) achieved remission (the score ≤ 14), 16 (59.3%) achieved treatment response (reduction in the score ≥ 18), and 20 (74.1%) achieved remission and/or treatment response. CONCLUSIONS: Acceptance and commitment therapy is feasible for persistent postural-perceptual dizziness and might have long-term effectiveness. However, a randomized controlled trial is warranted.

Association between marital satisfaction of female patients with persistent depressive disorder, and their own and husbands' autism spectrum disorder or attention deficit/hyperactivity disorder traits.

Aim: Patients' and spouses' neurodevelopmental traits may influence marital relationships, which are significantly associated with depressive symptoms. However, no studies have examined marital relationships in persistent depressive disorder (PDD) in terms of neurodevelopmental traits. This study aimed to explore the association between the autism spectrum disorder (ASD) or attention-deficit/hyperactivity disorder (ADHD) traits of female PDD patients and both partners' (patient and husband) marital satisfaction. Methods: A cross-sectional online survey was administered during two predetermined consecutive months at seven institutions. Participants were female outpatients who fulfilled the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition criteria for PDD and their husbands. The instruments of the study were the following validated surveys: the Quality Marriage Index (QMI), the Autism-Spectrum Quotient Japanese version-21 (AQ-J-21), and the Adult ADHD Self-Report Scale Part A (ASRS Part A). Results: The patients' AQ-J-21 showed a positive significant association with their QMI in all patients who responded to this study's questionnaire, whereas among couples wherein both patient and husband responded, the ASRS Part A exhibited a positive significant association with the patients' QMI. Conversely, the husbands' ASRS Part A exhibited a negative significant association with the patients' QMI. Conclusion: The patients' ASD and ADHD traits may play a positive role in the marital satisfaction of female PDD patients, while their husbands' ADHD traits may play a negative role. For female PDD patients with low marital satisfaction, it may be important to consider whether their husbands have ADHD traits; if so, it may be necessary to develop intervention strategies focused on the traits for improving the low marital satisfaction. However, our conclusions are not sufficiently convincing.

Cognitive-behavioural therapy for chronic subjective dizziness: Predictors of improvement in Dizziness Handicap Inventory at 6 months posttreatment.

Background: Chronic subjective dizziness (CSD), which was superseded by persistent postural-perceptual dizziness as of 2017, has a great impact on patients' quality of life. Cognitive-behavioural therapy (CBT) is a promising treatment, with demonstrated effectiveness as a CSD treatment; however, no studies have examined positive predictors of its effectiveness in the long term.Aims/objectives: This study aimed to examine predictors of improvement in the Dizziness Handicap Inventory (DHI) in patients with CSD at 6 months after CBT.Materials and methods: Thirty-seven patients with CSD who were recruited from April 2012 to November 2014 and completed group CBT were analysed. Single and multiple regression analyses with forward-backward stepwise model selection method was used to examine the independent predictors of long-term improvement in the change score of DHI.Results: Presence or absence of comorbid anxiety disorders (p = .023) was a significant positive predictive factor for improvement of DHI from pretreatment to 6-month follow-up.Conclusions and significance: The presence of comorbid anxiety disorders predicted considerable improvement of DHI from pretreatment to 6-month follow-up. Group therapy including interoceptive exposure using vestibular rehabilitation, along with psychoeducation and behavioural experiments with graded exposure, may be particularly suitable in treating patients with CSD.
